This invention relates to a process of making an improved food productand more particularly a food product containing ingredients which arebeneficial in decreasing or eliminating gastric disturbances in thedigestive tract.

One of the objects of my invention is to produce an improved foodproduct having embodied therein and finely dispersed throughout the massingredient in the form of charred organic material which is beneficialin decreasing or eliminating gastric disturbances in the digestivetract.

Another and more specific object is to produce a food product which hascharcoal finely dispersedthroughout its mass.

Still another object is to produce a new. process of finely dispersingthroughout the mass of a food substance an ingredient which isbeneficial tothe digestive tract of the consumer,

A further object isto embody. in a food product by a filtration processan ingredient beneficial to the digestive tract.

Yet another object is to so filter from a soluthat there will be addedcharcoal.

Other objects of my invention will become apparent from the followingdescription of my new food product and the process by which it way ofexample, reference product.

My improved food product comprises a mash having food values dividedingredient in which is dispersed a finely beneficial in the digestion ofthe product, particularly in the decreasing or elimination of gastricdisturbances resulting from gases formed during digestion, suchincharred organic material such charcoal, bleached bone char I am awarethat food products class for which my improved food product isespecially suited, have as a contained ingredient pulverized charcoalbut this charcoal has merely been added into the food substance bystirring and agitating with a suitable mixer gredient being a and thelike.

when the food substance is in bulk. Consequently there is not athorough'dispersing of the charcoal with the result that the consumermay separate out as much of the charcoal as possible and thus not obtainthe full benefits.

Furthermore, without a complete dispersion of the charcoal throughoutthe food product a uniform benefit also does not result.

The new food product may embody as the food July 26, 1945,

-7 Claims. (0]. 99-'2) substance grain pulp, fruit and vegetable pulpand pulp from any rind products. This mod substance generally results.from processes employed to extract certain ingredients from originalmaterial as, for example, oil from soybeans, sugar irom sugar beets,Juices from fruits and vegetables, etc. As a result of extractionprocesses the food substance forming the food value material of my newproduct is in solution and when filtering it out of such solution toform a mash the ingredient, such as charcoal or bleached bone char, isembodied therein.

The preferred method employed is to coat a filter medium such as canvas,cocoa matting, etc, with the ingredient to be mixed into the foodsubstance. The type of filter to be used can be either the leaf type ordrum type. A preferred type of filter is the Syncro-drum Continu-coatfilter disclosed by the application of C. Lynn Peterson et al., Ser. No.440,858, filed April 28, 1942, now Patent Number 2,403,021, issued July2, 1946, for Method and apparatus for filtration" or the Continu-coatdrum filter with pressure roll as also disclosed in the sameapplication. After the cost of the ingredient to be added is placed onthefilter medium the solution containing the food substance forming thefood material or the new food product is filtered food material is .wetand is being drawn into the coat of the ingredient, there will be aninterspersing of the two which the wetness of the materials. Suction isused during the filtering and thus the food material will be pulled intothe coat of the ingredient. After a cake is formed on the filter mediumit is scraped off by a suitable scraper and to assist this scraper inremoving the cake, air is blown through the filter medium in an outwarddirec tion. The action of the scraper and the air current together willproduct additional mixing and dispersing Of the ingredient in the foodsubstance. The' final result will be a food which will have embodiedtherein and finely dispersed therethrough the desired added ingredientto aid in digestion by being beneficial in decreasing or eliminatingtroublesome gastric disturbances. The percentage of the ingredientdispersed in the product can be varied by varying the amount coated onthe filter medium.

A specific example of the food product and the method of making same,which embodies my invention.- would be one in which finely dividedcharcoal is dispersed in a soy is further assisted by bean flake mash.

" filter medium toward which might be present.

absorb any gases.

food product would determine the percentage of charcoal suspended in theslurry. After this charcoal is coated onto the filter medium thesolution containing the suspended soy bean flakes is passed through thefilter medium with the aid of suction. This will cause the soy beanflakes to become dispersed into the charcoal particles and vice versa,and since both the fiakes and the charcoal are wet there will resultadditional interspersing. The cake formed on the filter medium may bewashed with water, if desired, further interspersing the soy bean flakesand charcoal. The cake is next scraped off of the filter medium by asuitable scraper and to aid in the removal of the cake air underpressure is forced through the the cak side. Scraping oil of the cake,together with the air pressure, will result in a certain amount ofagitation and mixing of the resulting product, thus bringing about anadditional dispersion of the charcoal in the soy bean flakes.

The result will be a mash forming my improved food product. If the foodproduct is intended for cattle feed it should contain about five to sixpercent of charcoal and if it is intended for chick feed it shouldcontain approximately four percent, this percentage being controlled, aspreviously noted, by the amount of charcoal deposited on the filtermedium. The dispersion of the charcoal in the soy bean flakes isconsiderably greater than any dispersion that can be obtained by merelytaking the mesh resulting from filtering the soy bean solution andadding the charcoal and mixing it by some mechanical mixer. The productfrom my improved process will not contain any large chunks or lumps ofcharcoal. The charcoal will be so finely dispersed in the product thatthe animal consuming it cannot separate portions of the charcoal andavoid taking it with the soy bean flakes. Because it is finely dispersedthrough the soy bean flakes it will have a, very uniform and continuouseffect in the digestive tract or the animal to prevent or eliminategastric disturbances. By having finely divided charcoal intermixed withall the soy bean flakes there will always be charcoal present in thedigestive tract during digestion of the flakes to absorb any gases caseit there were clumps as part of the charcoal Furthermore, with clumps ofcharcoal there would be a tendency for these to become coated overduring the digestive process any they would be ineffective for thepurposes for which they are added to the food.
